I TRIP MECHANISM FQR DYEING MACHINES.

To (417 whom it may concern:

Be it known that we, JOHN H. Guns and DONALD M. GILES, both residing atPhiladelphia, county of Philadelphia, and State of Pennsylvania, haveinvented certain new and useful Improvements in a Trip Mechanism forDyeing Machines, of which the following is a specificationv My inventionrelates to dyeing machines and more especially to those of the type inwhich yarn in the form of skeins is treated by being passed through avat containing dye liquor. ary to support the yarn in the skein formbetween two series of yarn sticks mounted horizontally in inner andouter frames, the frames being in the form of wheels and being supportedin a vat. In these machines the skein supporting structure is movable asa whole into and out of the dye vat and the sticks are removable fromthe heads of the frames so that the skeined yarn may be placed inposition thereon. When the yarn is supported on the sticks in the usualman ner the supporting shaft is revolved so that successive sticks aboutthe periphery of the supporting members will be passed through theliquor. In this way successive strands are immersed in the dye and inorder that 30 the entire massof yarn in a single skein may be treated sothat the color will be even, it is necessary that the skein be moved onthe supporting member. This is accomplished by providing a suitable starwheel or ratchet movable with each stick of one series and operated by atrip mechanism so that as each star wheel passes beneath the trip, itwill be given a partial rotation, this causing the yarn to be movedrelative to the sticks so that a different portion of the skeins will beimmersed as the supporting frames are revolved. It is necessary that thetrip have a resilient mounting so that should the yarn become tangled ona pair of-sticks in such a way to prevent the partial. rotation. of thesticks the trip will yield so that the yarn will not be broken.

It will be understood, of course, that though the machine is regularlyrevolvable in. a single direction only, it some times happens that whenit is brought to rest, the shaft will be moved a short distance in thereverse direction. It is necessary in such event that the trip be ofsuch form that it will be thrown out of action so as not to cause thestar wheel to be reversely rotated In such machines it is custom-Application filed April 19, 1922.. Serial No. 555,564.

inasmuch as this will hav a tendency to tangle the yarn strand.

Une object of this invention, therefore, is to provide a new andimproved trip mechanism for a dyeing machine of the class described,such trip mechanism providing means for exposing successive portions ofthe yarn skeins to the action of the dye liquor and having a positiveaction when the machine is rotated in one direction, except in the caseof undue stress, and being thrown out of action when the machine isreversed.

Another object of the invention is to pro vide a trip mechanism for adyeing machine of the class described, such mechanism providing a simpleand effective means for exposing successive portions of the skeins t0the action of the dye liquor and being so arranged as to prevent unduestress being put on the skeins and to prevent the movement of the skeinsin the reverse direction.

Another object of the invention is to proide a new and improved tripmechanism for a dyeing machine of the class described which shall besimple in construction, formed of a few parts not readily madeineffective by wear and one which shall be cheaply constructed.

Other objects and aims of the invention, more or less specific thanthose referred to above, will be in part obvious and in part pointed outin the course of the following description of the elements,combinations, arrangements of parts and application of principles,constituting the invention; and the scope of protection contemplatedwill be indicated in the appended claims.

lVith this and other objects in view, refer- -95 ence is now made to thedrawings in which are shown various preferred forms of embodiment of myinvention. I

In the drawings Figure 1 represents a vertical cross-sectional view of adyeing machine showing my invention in place.

Figur 2 is a front view in detail of the various parts constituting myinvention.

Fig. 3 is a side view in detail of the construction otherwiseillustrated in Fig. 2..

Figures l and 5 are front and side. views respectively of a modifiedform of my device. I a .Figures 6 and 7 are front and side viewsrespectively of another modification of my invention.

With reference now to the drawings in which similar reference charactersrefer to similar parts throughout the several views thereof; thereference character l denotes the body structure of the machine, in thebottom of which is located a semicylindrical dye vat 2 supplied with dyeliquor through a pipe 3 and having a suitable outlet gate 4.

Mounted in the ends of the body structure 1 in slot-like bearings 5 is ashaft 6 upon which is mounted a pair of outer frames 7 and a pair ofinner frames 8. in Figure 1 there is shown but one member of each pairof frames and it will be understood that the structure shown in Figure 1is duplicated at the other end of the shaft. Running between the pair ofheads two rows of yarn sticks 9 and 10, the yarn sticks forming theelements of the inner and outer rows being removably mounted. on starwheels 11 journalled upon the heads so that the skeins may be placedthereabout, a sin gle skein running between corresponding sticks of theinner and outer rows. hen the sticks are in place with the yarn woundabout them, the inner sticks are loosely held in hearings in the innerstar wheels while on the outer star wheels the bearings for the sticksare rigidly secured whenv in operative position. Loosely mounted on theshaft 6 is a guide rod 12 extending outwardly and projecting through aswivel guide 13. Upon this guide rod 12, is mounted the trip mechanismat a point adjacent the row of star wheels so that the points of thestar wheels will be engaged thereby as the shaft 6 revolved.

As has been explained, the shaft 6 is supported in bearings in anarcuate slot 5 to the end that the shaft with the stick supporting headsthereon may be mounted bodily out of the dye vat so that the dyed skeinsmay be removed and new ones substituted on the sticks. By providing aloose mounting for the guide rod 12 on the shaft and using a swivelguide 13, this permits the shaft with its attached members to he swungout of and into operative position without necessitating thereadjustment of thetrip mechanism relative to star wheels.

The general construction of the dyeing machine so far described is offamiliar form and is inserted herein in order that the operation of mynew improved trip mechanism will be readily understood. reference now toFigures 2 and 3, it will be seen that the trip mechanism consists of twoparts, a movable arm and a resilient stop for one end of the arm.Mounted on the guide rod 12 is a suitable clamp 1 1 on which ispivotally mounted at 15 anarm 16.

The arm 16 projects downwardly from the pivot so as to lie in the pathot the outwardly extending arms ot the star wheels 11. The arm 16 has anupward extension 17 and mounted on the guide rod 12 at a point slightlybeyond the clamp 14. is a sec- With I naea'rea 0nd l9.

clamp 18 to which is attached an arm In the end of the arm 19 is secureda bolt 20 about which. is coiled a spring 21 and mounted on the boltadjacent its forward end is a stop held against the under side of thearm 19 by the spring 21. lhe stop 22 projects downwardly and is normallyengaged by the extension 17 of the arn'i 16. Adjacent the pivot pointthe arm 16 has an extension at right angles on which is mounted a weight23.

It will be seen that as the main shaft revolves in the counter clockwisedirection to. outwardly extending arms of the star wheel will come incontact with the arm 16. En der normal conditions the arm 16 will b heldsufliciently rigi lly on its pivot 0;. means of the spring 21 and stop22 so that the star wheel in moving past the arm 16 will be rotated byone tooth. The outer sticks as will be seen have a square cross sectionand a partial. revolution of the stick will cause the skeined yarn to bemoved trom one stick to the other a slight distance. cessive portions ofthe skeins will be brought to the periphery of the dyeing frame so thatas the operation is continued all the yarn in the skein will be immersedin the liquor.

In the event that the yarn becomes tangled on the sticks and is not freeto move from one stick to the other, the star wheel on the stick onwhich the tangled skein is mounted will offer resistance to the actionof the trip and when the resistance exceeds the pressure of the springagainst. the stop the trip will yield with a partial clockwise rotation.This forces the stop 22 to compress the spring and thus permits thepoint of the star wheel to ride under the trip. This will prevent theyarn being broken or undue stress being put upon the star wheel and tripIt will be understood that the star wheels are provided with ratchetdevices not shown to prevent retrograde movement, and if shaft 6 shouldbe moved reversely, the teeth of the star wheels will engage the otherface of the trip, which is free to move upwardly out of the way, theweight 23 restoring the trip to operative position when the star wheelin question has moved from beneath the trip.

in Figures 4 and 5 a modified form of trip structure is shown. In thiscase the trip arm 16 is pivotally mounted on av clamp 1 1-. located onthe rod 12, the trip arm being provided with an. offset weight 23. Theextension 24 of the arm 16 is given a torked shape. as indicated inFigure 5 at 25--25. and in the fork so formed there is mounted by meansof a clamp 18 on the rod 12, a downwardly extending arm 26, carrying abolt 27 about which is coiled spring 28. Mounted loosely on the loolt27, near its forward end is a shield-like lt will follow from this thatsucstop 29, which is of such shape as to be engaged by the legs 2-325.As indicated at 30, the extension 24, which is in the nature of afollower. has a curved shape, and as the trip arm 16 is rocked uponundue stress, which would prevent the turning of the star wheel, it willbe understood that the arm 16 will move on its pivot, and that theextension 24 will act against the stop 29 and force it along the bolt soas to compress the spring 28.

The curved surface of the extension 24 is of such form that the pressurewhich will be put against the stop 29, to press the spring. will alwaysbe a direct thrust, acting in a line parallel'to the bolt. This willprevent the stop from binding against the bolt, which would result inthe trip arm '16 being held in position so as to resist movement whenengaged by the star wheel. lVere it not for the direct thrust providedfor, the binding of the stop against the bolt might result in the trip16, causing a r0- tation of the star wheel when the yarn was entangled,and this might easily cause a breakage in the yarn. In the caseof thereverse movement of the yarn supporting heads, the trip will be movedfreely out of position. the extension 24 being rocked away from the faceof the stop. When the star wheel passes from under the trip in a reversedirection, the weight 23 will return the trip to operative position,with the extension 24 bearing against the stop.

In Figures 6 and 7 there is shown another form of modification in whichthere is provided a single clamp 31 mounted on the guide rod 12. Clamp31 is provided with an offset extension 32 in which is mounted a pin 33.Mounted pivotally on the end of the pin 33 there is a downwardlyextending trip arm 34 which projects into the path of the teeth of thestar wheels and which is provided with an offset weight 35. Beyond thepivot 34 is an extension 36 and coiled about the pin 33 is a spring 37,one end of which is anchored in the extension 32, the other end 38bearing against the extension 36 and the spring being so disposed as tooffer resistance to the clockwise movement of the trip on its pivot.

The operation of the device is similar to that of the forms previouslydescribed.

When the trip engages the projections of the star wheels, under normalcircumstances,

the wheels are revolved. but the trip yields under unusual stress. Uponmovement in the reverse direction of the shaft of the dyeing machine,the trip will ride over the teeth of the star wheels and be returned tonormal position by the offset weight.

It will be seen that the trip mechanism herein set forth is simple andone adapted to attain the objects mentioned. It provides a device whichwill rotate the star wheels and thereby expose different portions of theyarn to the action of the dye liquor under normal circumstances, and onewhich will yield so as to become inoperative upon the occurrence ofconditions of excessive stress upon the yarn or when the machine isreversed. The mechanism can be readily et in operative position, andonce so located it requires no further attention. It will be understoodalso that the springs may be readily replaced by others of differenttension depending upon the character of the yarn to bctreated. It ispossible to substitute other resilient mountings in place of the springsshown, the springs being here illustrated as being a simple andconvenient means of producing the desired end.

As many changes could be made in this construction without departingfrom the scope of the following claims, it is intended that all mattercontained in the above description or shown in the accompanying drawingsshall be interpreted as illustrative only and not in a limiting sense.
